THK LBG Series Rotary Ball Spline with Gear

The THK LBG Model Rotary Ball Spline with Gear is a unit-type rotary ball spline based on the LBR series, featuring a compact, fully integrated structure. Gear teeth are formed on the flange circumference, and radial and thrust bearings are built into the spline nut, allowing the unit to support both rotation and load handling within a single assembly.

This design makes the LBG model ideal for torque transmission mechanisms driven by the spline nut, particularly in compact systems requiring reliable rotary and linear motion integration.
